"To deal with spirit flames, my Fiend Silkworms are the most useful. I'll put out this mass of spirit flame."
Hearing this, Qing Kong immediately stepped forward and waved his hand, scattering a cloud of dull gray silkworms.
After these silkworms fell into the crimson spirit flames, not only were their bodies not burned black, they instead swam about freely within them.
Before long, the Fiend Silkworms had devoured every last bit of the spirit flames. Their surfaces became glossy and bright, while their auras visibly grew stronger.
Clearly, Qing Kong's Fiend Silkworms had gained some benefits by devouring the crimson spirit flames.
However, compared with the gains from this expedition, the small advantage Qing Kong had taken was nothing.
Thus, although Luo Hong and the other three all understood perfectly well, they tacitly chose not to say anything.
"Eh? Why is there a groove at the bottom of this cauldron?"
Just as Qing Kong was about to retrieve his Fiend Silkworms, he suddenly noticed something through their eyes and immediately asked in puzzlement.
Hearing this, Luo Hong and the others turned to look. Sure enough, they saw a long vertical groove at the bottom of the Three-legged Black Cauldron.
First, the spirit flames had concealed it; second, the cauldron blocked spiritual sense. That was why none of them had noticed it earlier.
"Judging from the Restriction Runes around this groove, it definitely wasn't formed by an impact, nor was it used for pill refinement. I reckon this is the key to opening the cauldron."
After examining it for a moment, Ling Feng was the first to voice the thought shared by all five of them.
"I also think this cauldron needs something like a key to be opened normally, but where are we supposed to find one?"
